The invention contemplates a binocular barrel system as for use in a microscope wherein an oriented target line at the focal plane of the eyepiece is kept at consistently the same orientation with respect to the viewed object, in spite of the fact that the eyepiece housings are swivel-mounted to the barrel for accommodation to the interpupillary distance of the observer. A parallelogram system so coordinates rotation of the target-line support at the eyepiece, with rotational displacement of the eyepiece about the barrel, that the correct orientation is seen by any and all observers, regardless of individual differences in interpupillary distance.
